There is nothing inherently 32- or 64-bit about Tomcat except for (a)
the service-runner and (b) the Tomcat native library (if you are using
it).

If you use the 64-bit service runner, you will need a 64-bit JVM.
There really isn't any particular reason to use a 32-bit JVM on a
64-bit OS at this point, so just go ahead and run the 64-bit version
and be done with it.

If you have a 32-bit OS then you have no options: you will require a
32-bit JVM. That limits your heap size. Upgrade to a 64-bit OS. All
modern CPUs are 64-bits, even if your vendor sold you a copy of 32-bit
Windows.

The version of Java really only has a minimum. The minimum version of
Java for Tomcat 5 was Java 1.4. Java 11 should work just fine.

HOWEVER, if you really are using Tomcat 5 (.0.x? .5.x?) then you
should know that there is a 100% chance that there are exploitable
vulnerabilities in that software that will never be patched. [1][2]
You should take the time to upgrade your Tomcat version before doing
pretty much anything else.

Actually... Windows server 2003? Java 1.5? Tomcat 5? It sounds like
you need to upgrade EVERYTHING (including hardware?) in order to be
able to safely operate a web service.
